如何仅在 PHP 中重写 URL? [英] How To Rewrite URL in PHP Only?

问题描述

我正在考虑一个 MVC(模型、视图、控制器)结构化站点.它托管在 smallbusiness.yahoo.com 上.(Apache) 他们将托管限制为 php(和 mysql)，我无法编辑服务器配置.这意味着没有 .htaccess 文件！找了很久的解决方案，都涉及到编辑服务器配置.我正在寻找一种仅用 php 本身重写 URL 的方法.

I have a MVC (Model, View, Controller) structured site that I'm thinking about. It's hosted on smallbusiness.yahoo.com. (Apache) They limit the hosting to php (and mysql), and there's no way I can edit the server configurations. That means no .htaccess files! I have searched for the solution for a long time, but they all involve editing the server configurations. I am looking for a way to rewrite URLs with only php itself.

我想做 URL 重写，以便控制器可以通过 URL 接收参数.我知道 Codeigniter 会这样做，但我确实想了解它是如何做到的.

I want to do URL rewriting so that the controller(s) can receive parameters through the URL. I know Codeigniter does this, but I do want to LEARN how it does it.

例如，像这样:

example.com/page.php?page=whatever

example.com/page.php?page=whatever

变成

example.com/page/whatever 或

example.com/page/whatever OR

example.com/whatever

example.com/whatever

我看过一些关于 $_SERVER['PATH_INFO'] 的例子，但我不明白它的作用.我试过了

I've seen some examples with $_SERVER['PATH_INFO'], but I don't understand what that does. I've tried

$_SERVER['PATH_INFO'] = '/';

但这并没有起到任何作用......将不胜感激！

But that did nothing... Help would be greatly appreciated!!

推荐答案

这是我能找到的最接近的东西.严格来说，即使是 WordPress 也会修改 .htaccess 以允许他们自己的模块来管理重写.我觉得奇怪的是，他们会完全禁止所有 .htaccess 更改.你试过了吗?甚至 ASP.NET 也需要修改 web.config 才能使用重写.

This is the closest thing I could find. Strictly speaking, even WordPress modifies the .htaccess to allow their own module to manage the rewriting. I find it odd that they would completely disallow all .htaccess changes. Have you given it a try? Even ASP.NET requires a web.config modification to use rewrites.

显然，如果 .htaccess 被完全禁止，最后一个解决方案将无济于事，但在您实际使用 PHP 的情况下，这种情况很少见.我可以看到他们不允许覆盖，但这通常只适用于索引和目录选项之类的东西.

Obviously the last solution wouldn't help if .htaccess is disallowed entirely, but that's rarely the case where you can actually use PHP. I can see them disallowing overrides, but that usually only applies to things like indexes and directory options.
